Over the decades, NASA astronauts have logged thousands of days in space, pushing the limits of human endurance and exploration. These astronauts often serve on long-duration International Space Station (ISS) missions, contributing to critical research on human health, spacecraft systems, and deep space habitability.
The Axiom-4 mission that roared into space on Wednesday with four crew members, includes Peggy Whitson, former NASA astronaut, who holds the record for highest cumulative days in space.
ISRO (Indian Space Research Organisation) astronaut and pilot Shubhanshu Shukla, and mission specialists ESA (European Space Agency) project astronaut Sławosz Uznański-Wiśniewski of Poland and HUNOR (Hungarian to Orbit) astronaut Tibor Kapu of Hungary are also part of the crew. Shukla will be the first-ever Indian to visit ISS.
The cumulative days in space record tracks the total time an astronaut has spent in space across multiple missions. From Peggy A. Whitson to Serena Sunita L. Williams, here’s a look at the top NASA astronauts with the highest cumulative time in space.
| NASA Astronaut | Number of Days |
|---|---|
| Peggy A. Whitson | 675 |
| Sunita L. Williams | 608 |
| Don Pettit | 590 |
| Jeff Williams | 534 |
| Mark Vande Hei | 523 |
